First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

excellent! movie selection just ok, but everything else was wonderful.

The seat cushions are absolutely lacking, not sure if they know the passengers are traveling for 14 hours straight, but the padding made our back and butt ache like crazy. The entertainment console had its own problems, either the headphone jack wasn't working or the power outlet via usb or ac outlet was not working. Not to mention the seat handles were not adjustable in some planes in the middle or on the aisle. Qatar/Indigo may be operating a very old fleet of planes to make as much profit as possible, but passengers may not be following them for long, should this treatment of its customers continue. Qatar/Indigo, wake up and do it right by your customers, or they may not be your customers anymore.

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

I wish I knew in advance that the connecting flight was by indigo air

Very efficient and professional staff. Food was good and so was entertainment selection.

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

Reason for travelling Tampa to Orlando is to fly Qatar Airline. we end up with American Airline. This was the miserable experience I ever had in my entire travel history. Flight attendants were rude. They hit my knee with the food cart and I was holding ice pack for 2 hours. I still have the pain after a week. WE boarded the flight twice because of the temperature inside the plan.

I had to stay in the airport 15 even with a hotel reservation..i was refused to inter to qatar cuz the hotel was outside the airport. They could have offered a solution. It was really exhausting for me and my family.

Delays on take off, delays at gate on landing, lugging lost to the ether. power on seats not working, couldn't work due to that and no WiFi. The crew was great and boarding was orderly if confused and rushed.

Mumbai airport is a nightmare! Especially going from domestic to international terminal (2). I almost missed my flight. Then i could not check in because I purchased on kayak to British airways and my first flight was an indigo (non partner). So they called me when I was at the security outside the terminal and told me I had a middle seat, not what I paid for! After talking to the desk agent, they could not help but it finally worked out. A bit stressful for no reason. Probably never buy from kayak again this type pf complicated tickets (multi cities).

They had us seating down for one hour just waiting on the plane

Flying with BA is always a good experience—even in economy class. It is better if in business and first class. Timely, breeze through security and timely connections

Easy, straightforward boarding process. Flight attendant was lovely and attentive, food was delicious - especially dinner, I had the roasted chicken in a mushroom sauce with potatoes - and entertainment selection was top notch. I would fly with BA again.

We waited at BOS at the gate for an hour and couldn’t get a drink or anything. Once in the air the service, food and ride was excellent.

Crew was good. Seat was worn but overall okay. The infotainment system is outdated and needs to be updated. BA should provide free WiFi for club world/business class passengers.

I really liked it when the First Officer mentioned that we could see Paris out of the window on the left.

Pilot announcements were clear. Boarding is too slow compared to budget carriers.

My enetertainmnet screen was broken. Lost my bags. Almost missed my flight do to connection issues with (despite a request) ZERO help from crew. Food was edible. Potatoes pretty good even
